In the list of many theories of conspiracy, we find the beliefs of the platists.
According to the followers, NASA lies to the whole humanity while affirming that the Earth is round and lies also on space travel. The most famous society of platists, the Flat Earth Society, has therefore decided to organize an Antarctic cruise in 2020 to prove that the continent is only a great barrier of ice. But the party may be short-lived: all shipping is based on the fact that our planet is spherical.
Ships can locate themselves using a system called GNSS and this requires at least 4 satellites.
If the Earth were flat, it would only take three. Yet platists do not get discouraged and find new theories and arguments.
Last year, an American built a homemade rocket to test his theory. The American rapper BOB is also partisan and had launched a fundraiser to prove that the Earth is flat.
